WREFORD L. McCARTY, OF MEMPHIS, TENNESSEE, SSIGNOR TO AUTOMATIC MARKING COMPANY, Ol 1 AUGUSTA, GEORGIA.

Specification of Letters Patent.

Patented March 23, 190e.

Application led May 9, 1908, Serial No. 431,898.`

To all whom 'it may concern:

Be it known that I, W REEORD L. MCOARTY, a citizen of the United States, residing at Memphis, in the county of Shelby and State of Tennessee,'have invented a new and useful Inkin Roller for Printing-Presses, (Case 1),) o which the following is a specification.

This invention relates to printing presses, and its object is to provide an improved vl'orin of inking roller for snchprcsses wherein the ink will be contained in the roller and the lio'w therefrom be capable oi' regulation. l

The invention consists .of an improved form of inking roller arranged to contain ink therein and circumferentially perforated, tOOetherwith means to control the flow of inh therefrom. l'

Thel invention further consists in certain novel detailsvoi arrangement and combinations o'l parts, hereinafter fully described, illustrated in the accornl'ianying drawings, .and specifically set forth in the claims.

In the accompanying drawings like characters of reference indicate like )arts in the several Views and Figure 1 is a longitudinal lsection through he improved roller, a por# tion being shown in elevation. Fig. 2 is a view of one end oi said roller in elevation. 'Fi 3 is a transverse section thereof.

Tn the form of the invention here shqwn, there is provided a shaft 10, whereon is mounted a casing 11 provided with )erforations 12 therethrough. Extending etween the )erforations areflongitudinal and circum erential grooves 13, whereby the surface of the casing is broken up into a series of reticnlations. The casingA is covered with an absorbent cushion 'formed by, first a plying a layer of felt, as indicated at 14. here is then jrovided a layer of blotting paper 15, a secon layer of felt 16 is placed around the blotting pa er, and the Whole is covered with a layer of men, 'as'.at 17. The 'easing 11 is hollow interiori and the recess thus formed is frusto-conica in character, as indicated at 18. 'Vithin the casing 18 is mounted a frustofeonieal ink receptacle 19 provided K with perforations 2() extending therethrough. The perforations 2O are adapted to registel lwith the erforations 12 in the casing, and it parts be rotated with reference tothe other l lthe perforations20 and 12 will be thrown can readi y be understood that if one' of the more or less out of or into reis'ter with each other. .There 1s thus provi ed a means of .adjusting'the available area of said perforationsl In order to secure the parts in adjusted position the shaft 1() is provided with a screwthreaded ortion 21 on which is mounted a nut 22 a a ted to draw the casing and inl; receptacle mly together, the said shaft being provided with a collar 23 at the opposite end thereof. There is further rovided on the threaded portion of the shalt a jam-nut 24 to securely lock the nut 22 in position.

The casing 11 is provided with a recess 25 at theouter end thereof, and a in 26 is this recess. This pin serves as a limit stop to the rotation of the casing and receptacle withrelation to each other and at the saine time constitutes an index, suitable letters beimpresscd on the easing, to indicate When the device is used in connection with eared presses, it is preferred that a ear 29 mounted upon. one end thereof so t at the roller may be positively rotated.

In the 'operation of the invention, the receptacle having been supplied with ink, the device is rotated and the ink flows in the perforations 20 and k12 and is absorbed b the various strata of the absorbent pad,l eing distributed evenly thereover by means of the grooves 18. The flow is limited by the action of the roller 28 and may be further adjusted by rotating the casin and ink receptacle with relation to each ot er, the nuts 24 and 22 being loosened for this purpose. In order to provide means for readily rotating the parts 'there are here shown pin-holes 30 adapted-to receive the pins of an ordinary spanner.

What is claimed is:- 1. In an 111km roller, a casing and an absorbent cover t erefor, comprising-an inlmounted on the ink receptacle to ie within ioo4 ner layer of felt, a second layer of blotting material, a third layer of felt, and an exterior layer of linen.'

2. ln an inking roller, a circumferentially perforated ink reservoir, and a hollow cylin` drical closure of a diameter greater than one halfy the diameter of the interior of the ink reservoir adapted to cover successive perforations.

' 3. In an inking roller, a circumferentially perforated ink reservoir provided with an interior circular in cross section, and a cylinder held Within said reservoir toI form a hollow c lindrical closure lof a diameter greater t 1an one half the diameter of the interior of the ink reservoir adapted to cover successive perforations. j

vet. In an inking roller, a perforated ink reservoir having a frusto-comcal exterior, a casing therefor to it said ink reservoir rovided with perforations coincident with tliiose of the reservoir, means to rotate said casing with reference to the reservoir and vary the alinement of said perforations, and means to lock the casing and 'reservoir in adjusted position.

5. ln an inking roller, a perforated ink reservoir having a frusto-conical exterior, a

casing therefor toit said reservoir and rovided with perforations coincident with t ose of the. reservoir, means torotate said casing with reference to the reservoir and vary the alinement of said perforations, means to lock the casing and reservoir in adjusted position, and anabsorbent cover fors'aid casing.

6. ln an inking roller, a perforated ink reservoir having a frusto-conlcal exterior, a casing 'therefor to fit said reservoir provided with perforations coincident with those of the reservoir, means torotate said casing with reference to the reservoir and vary the alinement of the said perforations, means to-lock the casing and reservoirin adjusted'position, an .absorbent cover for said casing, and a closure adapted to cover successive perforations.

7. A perforated ink reservoir and a hollow cylindrical closure of adiameter greater than one halfthe diameter of the interior of the 1 ink reservoir in constant operative relation 50 t those perforations which tend to become speractive. l

8. A perforated ink reservoir, and a hollow cylindrical'closure of a diameter greater than one half the diameter of the interior of the ink reservoir contained therein in constant operative relation to those perforations which tend to become superactive. 9. A perforated ink reservoir, and a hollow cylindrical closure of a diameter greater than one half the diameter of the interior of the ink reservoir freely movable therein and in constant o erative relation to those perforations whic tend to become superaetive, 10. An ink reservoir provided with l*valved perforations, and a hollow cylindricallosure of a diameter greater than one half the diameter of the interior of the ink lreservoir in constant operative relation to -those perforations which tend to become superactive, and operating independently of the available area of the erforations.

1 An in reservoir provided with valved per orations, and a hollow cylindrical closure of a diameter greater than one half the di# ameter of the interior of the ink reservoir contained therein in constant o erative relation to those perforations 'W ich tend to v'become superactive, and, operating yindependently of the available area of the perforations.

12. An ink reservoir provided with valved perorations, and a hollow cylindrical closure of a diameter greater than one half the diameter of the interior of the ink reservoir freely movable therein, in constant operative relation to those perorations which tend to become .superact1ve, and operating independentlyof the available area of the perforations. t

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.v
